Remote controlled miniature 3 frequencies generator

Basically I need to be able to generate 3 different frequencies (10Hz, 400Hz, 10kHz) that are 5Vpp with 0.01-0.03mA. All 3 frequencies need to be independent of each other, meaning each one can be turned on/off irrelevant of the state of the others.

Example, all can run at the same time, or just 2 can run at the same time or any combination, etc. The frequency generating circuit needs to be able to fit on a PCB about 1inch x 2inches size, be able to run for 60 mins and can be controlled in a very simple way from a remote control. The frequency generating circuit will also should also be powered by a small replaceable DC battery , Lithium-Ion most likely.

I think the remote can be made to have simply 3 buttons , one for each frequency, where each button turns each frequency on or off. It should be able to operate within 10ft of the the frequency generating circuit.

Attached is also a small conceptual diagram that I came up with... Of course there might be other and more efficient or simple ways to do this ...Please advice! What is the simplest and smallest way built this? I would like to built a functional prototype by the end of this month.

Thanks!

I would use a single chip microcontroller with several PWM outputs (three, one per each frequency). There are much simpler ways to do it (like just switching in or out fixed oscillators), but it's more components, More
